Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a threadable bearing. Background Art

[0002] A sensor is a detection device that can sense the information being measured and convert the sensed information into electrical signals or other required forms of information output according to certain rules. When the sensor is in use, a threading bearing is required to thread the line through the threading bearing. Existing bearings usually have harness holes for threading. Since the size of the harness hole cannot be changed after it is opened, when the harness is more and thicker, it cannot be passed through the bearing. When the harness is less and thinner, the harness is too loose in the threading hole.

[0003] The existing patent (Announcement No.: CN209195961U) proposes a bearing, including a bearing inner ring and a bearing outer ring sleeved outside the bearing inner ring, a retaining frame is provided between the bearing inner ring and the bearing outer ring, a plurality of rolling bodies are provided on the retaining frame, and dust covers are fixedly connected at both ends of the bearing outer ring, a circular through hole is provided on the dust cover, a circular plate is concentrically provided in the circular through hole, and the upper and lower ends of the circular plate are rotatably connected to the circular through hole through a short shaft. The technical problem solved is that it is troublesome to add lubricating grease to the inside of the bearing in the prior art, and the dust cover needs to be removed, which is cumbersome to operate and inefficient. The advantage of the utility model is that lubricating grease can be added to the inside of the bearing without removing the dust cover, and it is very convenient to open and close the opening for adding lubricating grease, which saves time and improves the efficiency of adding lubricating grease.

[0004] The above-mentioned bearing adopts a technical solution to solve the problem of troublesome adding lubricating grease into the bearing, in which both ends of the outer ring of the bearing are fixedly connected with dust covers, and a circular through hole is provided on the dust cover. A circular plate is concentrically arranged in the circular through hole, and the upper and lower ends of the circular plate are connected to the circular through hole by a short shaft. The problem with this solution is that although it solves the convenience of adding lubricating grease to the bearing, it still does not solve the problem that too many wire harnesses cannot pass through the bearing or too few wire harnesses become loose when passing through the bearing. Therefore, we propose a threadable bearing to solve the above problem. Utility Model Content

[0005] The utility model provides a threadable bearing, which solves the current technical problem of mismatching when a wire harness passes through the bearing.

[0006] In order to solve the above technical problems, the utility model provides a threadable bearing, including a bearing inner ring, a through groove perpendicular to the bearing inner ring, clamping components symmetrically distributed in the through groove, two clamping components are fixed in the through groove, and a wiring harness is inserted between the two clamping components.

[0007] Preferably, the clamping assembly comprises an elastic component and a clamping plate, the elastic component and the clamping plate are fixedly connected, a side of the clamping plate away from the elastic component is inlaid with a plurality of friction blocks, and sliding blocks are fixed on both sides of the clamping plate.

[0008] The above technical solution is adopted: the clamping assembly includes an elastic component and a clamping plate, the clamping plate is used to clamp the wiring harness, the elastic component and the clamping plate are fixedly connected, when the wiring harness is inserted between the two clamping plates, the wiring harness squeezes the clamping plate, and the clamping plate squeezes the elastic component. At this moment, the elastic component gives the clamping plate a rebound force, so that the two clamping plates clamp the wiring harness, and a plurality of friction blocks are embedded on the side of the clamping plate away from the elastic component. The friction blocks prevent the wiring harness from being separated from the clamping plate when being clamped between the two clamping plates. Sliders are fixed on both sides of the clamping plate, and the sliders move in the slide groove so that the two clamping plates can move toward each other.

[0009] Preferably, two inner walls on both sides of the through slot are provided with sliding grooves, and two inner walls on the other two sides of the through slot are provided with seat grooves.

[0010] The above technical solution is adopted: sliding grooves are opened on the inner walls on both sides of the through groove, and the sliders on both sides of the clamp slide in the sliding grooves, so that the two clamps can be close to or away from each other, so as to facilitate the clamping of wire harnesses of different thicknesses. Seat grooves are opened on the other two inner walls of the through groove, so that the elastic component can be inserted and fixed in the seat grooves, ensuring that the range of movement between the two clamps in the through groove is large enough to clamp more wire harnesses.

[0011] Preferably, the elastic component includes a telescopic rod and a spring, the telescopic rod is sleeved in the spring, one end of the telescopic rod and the spring is fixed to one side of the clamping plate, and one end of the telescopic rod and the spring away from the clamping plate is fixed in a seat groove opened on the through groove.

[0012] The above technical solution is adopted: the elastic component includes a telescopic rod and a spring, the telescopic rod is sleeved in the spring, one end of the telescopic rod and the spring is fixed on one side of the clamp, and the end of the telescopic rod and the spring away from the clamp is fixed in a seat groove opened on the through groove. Through the compression and resetting of the spring and the extension and contraction of the telescopic rod, the clamp can move along the extension and contraction direction of the telescopic rod, so that the two clamps can clamp wire harnesses of different sizes and thicknesses.

[0013] Preferably, the sliding block is clamped in a sliding groove.

[0014] By adopting the above technical solution, the slider is clamped in the slide groove, so that the slider can move smoothly along the slide groove, thereby enabling the clamping plate to move horizontally.

[0015] Preferably, the friction block is made of soft rubber material.

[0016] The above technical solution is adopted: the friction block is made of soft rubber material. Since the outside of the wiring harness is wrapped by an insulating sleeve, the rubber material of the friction block can prevent the insulating sleeve on the outside of the wiring harness from being squeezed and damaged, while increasing the friction between the wiring harness and the clamping plate to prevent the wiring harness from falling off and loosening between the clamping plates.

[0017] Preferably, a bearing outer ring is disposed outside the bearing inner ring, a plurality of balls are disposed between the bearing inner ring and the bearing outer ring, and a bearing housing is disposed between the bearing inner ring and the bearing outer ring and at the top and bottom of the balls.

[0018] The above technical solution is adopted: a bearing outer ring is arranged outside the bearing inner ring, a plurality of balls are arranged between the bearing inner ring and the bearing outer ring, and a bearing cartridge is arranged between the bearing inner ring and the bearing outer ring and at the top and bottom of the balls, so that the bearing outer ring, the bearing inner ring, the balls and the bearing cartridge together form a bearing.

[0019] Preferably, the size of the clamping assembly is adapted to the through slot.

[0020] By adopting the above technical solution, the size of the clamping component is adapted to the through slot, so that the clamping component can move freely in the through slot.

[0021] Compared with the related art, the utility model has the following beneficial effects:

[0022] 1. Compared with the traditional bearing, the utility model is provided with a clamping assembly, a through groove is opened perpendicular to the inner ring of the bearing, the clamping assemblies are symmetrically arranged in the through groove, two clamping assemblies are fixed in the through groove, a wiring harness is inserted between the two clamping assemblies, the clamping plate in the clamping assembly is squeezed by the wiring harness, the clamping plate squeezes the elastic component, the elastic component exerts an elastic force on the clamping plate when being squeezed, so that the two clamping plates clamp the wiring harness, and can clamp and fix wiring harnesses of different thicknesses and different quantities. Compared with the traditional method of opening a wiring harness hole on the bearing for the wiring harness to pass through, the problem of too many and thicker wiring harnesses being unable to pass through and too loose wiring harnesses passing through the bearing due to too few and thin wiring harnesses is avoided.

[0023] 2. In the utility model, a friction block is provided, and the friction block is made of rubber material. Since the outside of the wire harness is wrapped by an insulating sleeve, the rubber material of the friction block can prevent the insulating sleeve outside the wire harness from being squeezed and damaged, and at the same time increase the friction between the wire harness and the clamping plate, preventing the wire harness from falling off and loosening between the two clamping plates.

[0030] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. Embodiment 1

[0031] like Figure 1-Figure 5 As shown, a threadable bearing comprises a bearing inner ring 3, a through slot 4 is opened perpendicular to the bearing inner ring 3, clamping components 5 are symmetrically distributed in the through slot 4, two clamping components 5 are fixed in the through slot 4, and a wire harness is inserted between the two clamping components 5;

[0032] It includes a bearing inner ring 3, a through groove 4 is opened perpendicular to the bearing inner ring 3, and clamping components 5 are symmetrically distributed in the through groove 4. Two clamping components 5 are fixed in the through groove 4, and a wiring harness is inserted between the two clamping components 5. The clamping plate 8 in the clamping component 5 is squeezed by the wiring harness, and the clamping plate 8 squeezes the elastic component 7. The elastic component 7 has an elastic force on the clamping plate 8 when being squeezed, so that the two clamping plates 8 clamp the wiring harness, and can clamp and fix wiring harnesses of different thicknesses and different quantities. Compared with the traditional method of opening a wiring harness hole on the bearing for the wiring harness to pass through, it avoids the problem that too many and thicker wiring harnesses cannot be passed through, and too few and thinner wiring harnesses are too loose after passing through the bearing. Embodiment 2

[0033] like Figure 1-Figure 5As shown, the clamping assembly 5 includes an elastic component 7 and a clamping plate 8, the elastic component 7 and the clamping plate 8 are fixedly connected, a plurality of friction blocks 81 are inlaid on the side of the clamping plate 8 away from the elastic component 7, sliders 82 are fixed on both sides of the clamping plate 8, the inner walls of both sides of the through slot 4 are provided with sliding grooves 42, and the inner walls of the other two sides of the through slot 4 are provided with seat grooves 41, the elastic component 7 includes a telescopic rod 71 and a spring 72, the telescopic rod 71 is sleeved in the spring 72, one end of the telescopic rod 71 and the spring 72 is fixed on one side of the clamping plate 8, and the end of the telescopic rod 71 and the spring 72 away from the clamping plate 8 is fixed in the seat groove 41 provided on the through slot 4, and the slider 82 is clamped in the sliding groove 41. In the groove 42, the friction block 81 is made of soft rubber material. Since the outside of the wire harness is wrapped by an insulating sleeve, the friction block 81 adopts rubber material to prevent the insulating sleeve outside the wire harness from being squeezed and damaged, and at the same time, the friction between the wire harness and the clamping plate 8 can be increased to prevent the wire harness from falling off and loosening between the clamping plates 8. The outer sleeve of the bearing inner ring 3 is provided with a bearing outer ring 1, and a plurality of balls 6 are arranged between the bearing inner ring 3 and the bearing outer ring 1. A bearing card shell 2 is clamped between the bearing inner ring 3 and the bearing outer ring 1 and at the top and bottom of the balls 6. The size of the clamping component 5 is adapted to the through groove 4, so that the clamping component 5 can move freely in the through groove 4;

[0034] The clamping plate 8 is used to clamp the wiring harness. The elastic component 7 and the clamping plate 8 are fixedly connected. When the wiring harness is inserted between the two clamping plates 8, the wiring harness squeezes the clamping plate 8, and the clamping plate 8 squeezes the elastic component 7. At this moment, the elastic component 7 gives the clamping plate 8 a rebound force, so that the two clamping plates 8 clamp the wiring harness. A plurality of friction blocks 81 are embedded on the side of the clamping plate 8 away from the elastic component 7. The friction blocks 81 prevent the wiring harness from being separated from the clamping plate 8 when being clamped between the two clamping plates 8. Slide blocks 82 are fixed on both sides of the clamping plate 8. The slide blocks 82 move in the slide groove 42, so that the two clamping plates 8 can move toward each other.

[0035] The inner walls of the through slot 4 are provided with sliding grooves 42 on both sides, and the sliders 82 on both sides of the clamping plate 8 slide in the sliding grooves 42, so that the two clamping plates 8 can approach or move away from each other, thereby facilitating the clamping of wire harnesses of different thicknesses. The inner walls of the through slot 4 are provided with seat grooves 41 on the other two sides, so that the elastic component 7 can be inserted and fixed in the seat grooves 41, ensuring that the range of movement between the two clamping plates 8 in the through slot 4 is large enough to clamp more wire harnesses. The elastic component 7 includes a telescopic rod 71 and a spring 72, and the telescopic rod 71 is sleeved in the spring 72. One end of the telescopic rod 71 and the spring 72 is fixed to one side of the clamping plate 8, and the end of the telescopic rod 71 and the spring 72 away from the clamping plate 8 is fixed in the seat groove 41 opened on the through slot 4. Through the compression and reset of the spring 72 and the extension and contraction of the telescopic rod 71, the clamping plate 8 can move along the extension and contraction direction of the telescopic rod 71, so that the two clamping plates 8 can clamp wire harnesses of different sizes and thicknesses.

[0036] Working principle: Figure 1-5As shown, after the bearing is fixed, the wire harness is passed through two clamping components 5 symmetrically arranged in the through groove 4. When the wire harness is large and thick, the wire harness squeezes the clamping plate 8 in the clamping component 5, and the clamping plate 8 squeezes the elastic component 7, so that the telescopic rod 71 in the elastic component 7 contracts and the spring 72 is compressed. After the wire harness is passed through, the elastic force of the spring 72 is restored, so that the two clamping plates 8 squeeze the wire harness, thereby clamping and fixing the wire harness. When the wire harness is small and thin, since the initial state is a fitted state, as long as the wire harness is inserted between the two clamping plates 8, the elastic component 7 will be compressed, thereby generating elastic force, so that the two clamping plates 8 squeeze and clamp the wire harness.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
